T0 aZZ wh0m it may concern:

Be 1t known that I, CLARENOEW. CLAUD,

a citizen of the United States, residing at Nashville, 1n thecounty of Davidson, State- This invention relates to attachments for' graphophones and particularly to that class of instruments employing a cylinder record.

One object of the invention is the provision of a means for shifting the carriage from one end of a record to the opposite end and thence bringing the needle into engagement with the cylinder to repeat the matter on the record.

Another object is the provision of'a means for lifting the needle clear of the record during the shifting movement and for bringing the same into engagement with the record at the end of the shifting movement.

A further object is the provisiomof a means for automatically accomplishingftiie above mentioned objects. And a still further object is the provision of a device which may be applied to most forms of graphophones now in use without. changing the construction of the same.

With these and other objects in view as the pres accompanying drawings and more particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the device may be made Without departing from the spirit or sacrificing-any of the advantages of the invention.

. In the accompanying drawings forming part of the specification :-Figure 1 is a front elevation of a graphophone showing the invention applied thereto andthe needle held in engagement with the cylinder. Fig. 2 is a similar view but showmg the position of the parts when the needle 1s out of engagement with the cylinder orduring the shifting movement. 3 is a detailed perspective of: the plate and its attachments. Fig. 4 is a plan view of the device.

Similar numerals of reference are employed to designate coriesponding parts throughout.

The invention consists primarily in a repeating device designed to repeat the contents of a cylinder .over and over again without the necessity of manually operating the vertically disposed base plate 5 between the carriage frame posts 6 and 7 the upper face of the box 8. The plate" 5 is oblong and provided on'one face andat its opposite ends with wedge blocks9 and 10, the opposed inner sides signed to bear against the opposite outer sides of the posts 6 and 7 in order to secure the plate 5 in vertical position, as shown in Figs. 1 and 2. The lower longitudinal side of the plate 5 is provided with notches 11 and 12 which receive the controlling screw 13 and operating lever 14 disposed on the upper face of the box.

The carriage slide is designated "by the numeral 15 and the carriage which slides thereon by the numeral 16-. .The carriage lever-is shown at 17 as extending outwardly from the carria e' and slide bar and performs the usual ering the carriage from and into'engagement with the cylinder. 7

The plate 5'is medially provided with a longitudinal opening 18 which receives the carriage lever 17. The opening 18 is suffi-v cient in length to move therein from one end of-itsjourney to the otherover the face of the record. The'end wall of theopening 18 which lies adjacent the finishing end v of the-cylinder is inclined lower side as'shown at 20, the parallel portion 20 terminating in a downward extension 21 parallel with t e opposite end wall.

What will subsequen lylbetermeda guide block is designated at' 22'. This block is substantially the shape, of a trapezoid in contour having its longer and parallel sides parallel with the longitudinal sides of the is disposed on f. which are de-' to permit the carriage lever.

outwardly as shown at 19, for a portion of its lengthand thence ex-- tended outwardly and parallel with the carriage and as shown in the drawings a notion of raising and lowacac a opening 18 and its opposite ends 23 and 24 inclined outwardly and in opposite ,directions. 'lhe length and width of the block is considerably less than that of the opening 18 and it is so disposed within the opening that its lower longitudinal side forms a narrow guide opening 25, with the corresponding side of the opening 18 and a similar guide opening 26 is-formed by the upper longitudinal side of the block and upper side of the opening 18. Connection between the block and face of the plate may be made in any manner and in' the present instance substantially U shaped straps are shown having their terminals secured to the face of the block and the face of the plate.

As before stated, the opening 18 is de-- moving toward the opposite end of the cylinder, the free end of the lever will enter the guide opening 26. lVhen the carriage arrives adjacent the finishing end of the cyl inder, the free end of the lever will be-in engagement with the inclined end 19, and further movement of the carriage will result in the inclined end depressing the lever, whereby the needle will be lifted'from engageme'nt with the cylinder and movement of the carriage stopped. ,When the parts are in these positions the lever will be in alinement with the lower guide opening 25, and in order to return the carriage to the starting end of the cylinder, the following construction is employed :By referring to Figs. 1 and 2, it will be seen that the carriage slide 15 is provided with a coil compression, spring 28, which completely encirele'sthejslide and has one end bearing on theend postti or that end adjacent the finishing en of thefcylinder and its opposite end bearing on the carriage lfi. Thus it will be seen as the carriage and needle are .moved over the surface of the cylinder the spring will be compressed until the lever has been depressed as before described and is in alinement with the guide opening 25,

whereupon the tension of the spring 28 will be sufficient to return the carriage to the starting end of the cylinder.

After the carriage has been forced by the spring 28 to the starting end of the cylinder, it is obvious that some means must be provided for elevating the lever in order to again bring theneedle in engagement with the cylinder and in order to accomplish this result the I following construction is employedz-By referring now to 1 and, 2, it will be seen that a leaf spring designated by the numeral 27, has one end sefacture and opening 18, and at a point substantially in alinement with the horizontal center of the block 22. The leaf spring is curved upwardly and outwardly as shown and its free end is disposed adjacent that end of the opening .18 remote from the inclined end 19. Thus it will be seen when the carriage lever arrives at a point adjacent the end of the passage 25,it will bear on the leaf spring 27,- and when the lever has reached the end of ,the block 22, the spring will move upwardly and lift the lever,

whereby the needle will engage with the cylinder.

From the foregoing it .can be seen that I have provided a structure which is comparatively simple and inexpensive to manuwhich can be readily applied to most forms of graphophones now in use. It will be seen that the device operates positively to both raise and lower the carriage and shift the same. that the spring motor which operates the graphophone will be sufficient to compress the springs 27 and 28, it being understood that the tension of these springs will be proportioned accordingly.

Having thus descr is claimed as new, is:

1..In a repeating attachment for graphophones, the; combination with the carriage, and carriage lever; of a plate having a guide opening for the carria e lever, member combined with said plate and cooperating with the sides of the opening for operating the lever to raise and lower the carriage, and means for shifting the carriage from one end of the opening to the other end.
